How to Harden Play-Doh in the Oven

Play-Doh comes in all colors from the basic red, blue, yellow and green to pastels and pinks. The possibilities of what you can create with Play-Doh are endless from fake food to colorful shapes. If you want to keep the creation, instead of allowing the Play-Doh to be remolded into something else, one way to preserve it is to bake it in the oven. While it may not last for a lifetime due to the tendency for it to crack, it will last long enough to admire.

     Put the cookie sheet in the oven and check every 10 minutes to see if it has hardened. You don't want to overcook the Play-Doh because it will become brittle when hard, which will ruin the creation.
